instale o gcc4.9 no Ubuntu14.04LTS com erro de “incompatibilidade de soma hash”

Question

Eu tento instalar o gcc4.9 no Ubuntu 14.04 e rodar:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update

com o seguinte erro:

...
W: Failed to fetch http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu/dists/trusty/main/binary-amd64/Packages  Hash Sum mismatch
E: Some index files failed to download. They have been ignored, or old  ones used instead

Eu insiro link no navegador recebendo resposta 'não encontrada'.

tente instalar mais:

sudo apt-get install gcc-4.9

com o seguinte:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

Problemas ao baixar a lista de pacotes devido a um Erro de "incompatibilidade de soma de hash" - isso não funciona para mim.

Qualquer sugestão será ótima para mim: -)

    

Answer 1

se você redimensionar a URL de volta para a pasta como esta

link

então funciona no navegador e você pode ver que há uma cópia compactada gzip e bzip2 do arquivo Packages. Você pode baixar este arquivo e colocá-lo em / var / cache / apt / archives / list ou / var / cache / apt / archives / ele pode pular a etapa com falha.

update: olhando a página do ppa eu posso ver que existe outro link que funcionará melhor, tente isso

sudo add-apt-repository ppa:ubuntu-toolchain-r/ppa
